Mashantucket Pequot
Museum
Intensive Garden Roof
Site Description: The green roof at the Mashantucket
Pequot Museum and Research Center was completed in 1998. It is located
off Rt. 214 in Ledyard, CT. The intensive garden roof 75,000 square
foot area has pathways, terraced gardens, grassed sitting area with
tables and a wooden deck.
Design
Detail: The Pequot goal installing the green roof was to blend
the museum into the landscape. The types of flowers that have
been planted are native non-native. Blueberry bushes and a strawberry
patch are also included along with an herb garden. There are gravel
paths designed to lead people through the gardens and sitting
areas. In the future paver blocks will be installed on some of
the gravel paths.
The green roof has an under drain system that collects stormwater
not absorbed by plants or evaporation. The under drain is piped
to a detention area approximately 100' from the building (picture
on right). The Pequots are not currently monitoring the amount
or quality of stormwater that leaves the roof. A site visit to
the detention area after heavy rains revealed no ponding or presence
of moisture loving plants (picture on bottom).
The Pequots report few negative aspects of the roof garden. One
problem encountered shortly after installation were a few small
leaks. The source of the leaks were hard to find as water is dispersed
throughout the roof but, once found and corrected there have been
no more problems.
